python3-txdbus: drop the six dependency

Browse Source 
Patch txdbus to use the dict methods, int, str, bytes indexing, next and
io.StringIO instead of the six helpers, and drop the runtime dependency.

Built for intel-corei7-64.

Subject: [PATCH] drop the six dependency
six is a Python 2 compatibility shim and txdbus does not need it on
Python 3: the iteritems/iterkeys/itervalues helpers are the dict
methods, integer_types and string_types are int and str, byte2int is
indexing the bytes object, six.next is next and six.moves.cStringIO is
io.StringIO.
Upstream-Status: Pending
